How do you calculate the total electric potential energy ( $U_e$ ) for multiple charges?

Sum all individual $U_e$ values, considering positive and negative signs.

How do you calculate the electric potential due to multiple charges?

Sum the individual electric potentials contributed by each charge.

Describe the process of finding the change in voltage ( $\Delta V$ ) using an integral.

$\Delta V = V_b - V_a = \int_a^b -E \cdot dl$ . Integrate the negative dot product of the electric field and displacement from point a to point b.

How do you calculate the total electric potential energy ( $U_e$ ) for multiple charges?

Sum all individual $U_e$ values, considering positive and negative signs.

How do you calculate the electric potential (V) of multiple charges?

Sum the individual potentials due to each charge.

How to calculate the change in voltage ( $Delta V$ )?

Use the formula: $Delta V = V_b - V_a = \int_a^b -E cdot dl$

What is the key difference between electric potential energy ( $U_e$ ) and electric potential (V)?

$U_e$ is the energy in Joules, while $V$ is the energy per unit charge in Volts (J/C).

Compare and contrast electric field lines and equipotential lines.

Electric field lines indicate the direction of the electric field, while equipotential lines connect points of equal electric potential. They are always perpendicular to each other.
